gineers mb. :ind other upper portions ol :in ordnungY lovoinotive, and which vforniv no part of the present invention, are omitted lron'l the drawings.

.Referring to the drawings, the numeral 9 .indicates the mein 'freine portion, which is zidvisebly of e substantially rectangular shape. illounted in suitable bearings below tbe freine ere the iront end rear tuiles 10 and l1, having mounted thereon the track Wheels l2. n

"Vitliin the mein 'freine is e supplemental treme 'i3 for supporting the Worlii'ig peres et the mechanism. This supplornentel freine is supported in e novel nnniner, e., provided Witli tliree points of suspension. The front point o'tsuspension is `formed by e transverse leef spring lll Wliioli is pivotally' connected et its Center by e pin to the eentrel portion of the front of the supporting freine.' The ends of the leef spring ere secured to the forward portion of the outer 'freine es clearly shown in Fig. 3. The two remaining points of suspension are provided et opposite sides of the inner supporting freine l3,-e ni;l between the ends of seid frame, tbe seid two points of suspension being formed by trunnions 16, "i6 which enter and ere turneble in the sides of the outer frame 9.

.The frontA reduced portion of the supplemental lranie supports tbe cylinder 1T ol :in ordineryr `gesoleneengine nieelianisnn The slieftof this engine mechanism is indicated by the numeral 18, and carries the usual ily Wheel 19, said ily wheel beving; its linb project-ingl rearwardly, as indicated by the nv.- inerel 2l). rlbis hub portion is lnrovidml with e square opening 2l whit-'li receives slidebly tliereinlbe squared forward end of n reversing sliett 22. This slm't is mounted in suitable bearings in tbe supporting freine i3, and is slidzible in seid lie'--iiiigs=.

Keyed to the sheft 22, e et distances spart thereon, are eene fri ien irlieels 23 and Surrounding tlv eli "li between these friction wheels, im eonteet Witn sind she-ft, ere sleeve se ions and 2G. vThe inner adjacent ends of tliese sleev; sect-ions ere provided. with ennnlerx-sliouiders 27, 27 which 'lit in ein annuler recess 2S formed in :i tubular betiiii'i" 2Q for seid sleeve sections. The 'forward end' of sleeve soi.

o is provided with e rigid bevel pin; end in tinn rigidly secured te tliis bevel By reason of the fact that the inner end 4of the sleeve sections 25 and 26 are provided with the annular shoulders 27 which fit in the annular Groove 2S, the said sleeve sections are hel-)d against longitudinal movement.

To the rear end of shaft 22 is pivoted a lever 34, the end of the lower arm of said lever being pivoted to an arm 35 rigidly connected to and projecting from a depending portion of the supporting fr ame 13. By turning this lever, it is obvious that the shaft 22 may be slid .either forwardly or'rearwardly, in accordance with the direction of turning the lever. y

Journaled in suitable bearings in the sup* lemental frame, and disposed at right angles to shaft 22, is a short chain shaft 36, the trunnions 16 being in the same center as said shaft. The inner end of this chain shaft has rigidly mounted thereon a beveled gear 37 which meshes with the two beveled inions 30 and 32. Shaft 36 has also keyed t iereon a double sprocket wheel, one sprocket member 33 'thereof having a sprocket chain 39 passing therearound, vsaid sprocket chain eading to and passing .arounda sprocketv wheel on the front axle 10. The other s rocket wheel member 41 has a sprocket c ain '42 assing therearound, said sprocket chain lea( ing to'a sprocket Wheel 43 on the rear axle 11. lFrom the fact that the trunnions 16 are centered with shaft 36, the vchains 39 and 42 are never tightened or loosened, notwithstanding movements imarted to the frame by reason of jars or virations.'

It will be assumed that the engine shaft rotates in the direction indicatedby the arrow which ,is applied to the fly said shaft. lf, now, it is desired that the locomotive shall run forward, the lever 34 is 5 0 grasped and pushed forwardly, so as to draw the shaft 22 rearwardly. This will bring the friction' c'one 23 into frictional clutching en gagement with the cup 31, and cone 24 out of frictional engagement with the cup 33.

Rotation of shaft 22 will through the engagement of cone 23 and cup 31 impart rotation to the sleeve section 25, and the rotation of this sleeve section will be imparted to the beveled gear 37 by reason of the mesh-l ing of bevel pinion 3 0 with .said beveled gear. In'view of the fact that bevel ear 37 is fast on shaft 36, this shaft is rotate in a forward direction, and consequently the two sprocket c hains 39 and 42 are moved sov as to turn the front and rear axles forwardly, and thereby sides of the ,outer frame 9, and the two secwheel 19 of` cause the locomotive to run in a forward direction.

lf it is desired to reverse the direction of travel of the locomotive, the reverse operation takes place, that is to say, the u )per-end .fm` of the lever 34 is grasped and pulled -rearl Wardly. This has the effect of thrusting shaft 22 forward to thereby bring cone 23 but of frictional engagement with cup 31, and cone 24 into frictional engagement with cup 75 33. This will have the effect of rotating sleeve section 26, which sleeve section, through the meshing of bevel pinion 32 with bevel gear 37 will cause shaft 36 to rotate in a direction toward 'the rear ofthe machine, and thereby through the movement imparted to sprocket chains 39 and 42 cause a rearward travelof the locomotive.

We prefer to' rovide improved forms of bearings for the front and rear axles 10 and 11. These bearings are illustrated in detail in Figs. 6 and 7 ofthe drawings, and consist of upper and lower sections 43 and 44 res ectively, the former being bolted to the tions being secured together by means of the bolts45.y These two sections 'of the bearing box are each provided with a half circular recess, which when the sections are adjusted together form a circular o ening in which are placed the two semi-ci`rcu ar bcarings46, 46, which semi-circular bearings are also of oval form inthe direction of thellength of the axle', l the recesses in the bearing box sections 43 andi/44 being similarly formed, as most cleary shown in Fig. 6. By this described form of bearing, when the wheels pass over uneven places in the track a rocking motion is per- 1n1'tted,vwhich allows the wheel and axle to move up or down, to thereby compensate for such unevenness. In order to prevent rotation of the semi-circular bearing sections 46, while yet at thesame time allowing for the free up and down-movement of the wheel and axle, we provide each bearing section 46 with an elongated recess .47, the length of said recess being in the direction of the length of the axle. A small pin 48 is passed through an opening in the upper bearing box section 43, and the lower end of this pin fits in said recess 47, From thisl construction, it will1 be evident that the upper bearing section 46 is prevented -from rotating on the shaft,4 while at the same time the rocking movement of s'aid bearing section with the shaft is not interfered .loo

Fig. 8.of the drawings illustrates a modified form of the reversing mechanism, whereby the locomotive is made capable of travel forward at a fast and slow speed, and also ca `a ble of travelingrearwardly at the same ast and slow speed. ln this form the shaft 22, and the .sleevesections 25 and 26 are arranged exactly as in the other form of construction, that is to say, the sleeve section 25 is provided 130 '1'5 as in said other construction, is loose thereon,
